TWI to 4 x PWM Driver

So after using this project in a sort of "vending-machine", im quite happy with the outcome.

I use 2 outputs for a DC-motor and the other 2 for two servos just as intended.

Yet i have two learnings i have for the next version or for whoever wants to build something like this:

1. Just one timer in PWM-mode for the Servo is not enough. The duty cycle is 255 steps over the whole 20ms while the servo only wants like ~10-30% of this whole range.

2. Temperature sensors on the output stage. While the overcurrent detection is fine, Having the full load on one output can overhat the Transistor when not careful.

But since everything else works, i can close this project for now and book it as a success.
